People's network radio beijing, 22 july (journalist li dong), was informed at a recent national exchange on the use of live viewing for conservation of tropical production of species resources, that the total stock of conservation of tropical production of species has steadily increased to over 90,000。
Tropical species quality resources are an important strategic resource for our country. China's tropics cover a land area of 480,000 square kilometres and cover some 20,000 higher plants. Since the 1950s, china has carried out several studies on the subject of species quality resources and the standardization of species quality resources in the tropics, as well as the conservation and use of species resources。
The head of the department of agricultural and rural reclamation (dia) of the ministry of agriculture and rural development has reported that 105 tropics stock reserves have been built throughout the country, and that more than 300 varieties of natural rubber and cassava have been developed for the conservation of ionoids, with the gradual scientific and normativeization of conservation of tropical species。
In terms of species, the conservation of the resources of the pyrotechnics and the dragon eye is the highest in the world; rubber trees and mangoes are the second largest in the world; and the conservation of the resources of the vital tropical crops, such as cassava, oil palm, pineapple and coconuts, is the fifth highest in the world, greatly enriching our strategic reserves of the resources of the tropical species。
In the area of seed innovation and species extension, by the end of last year, over 200 tropical crop varieties had been cumulatively validated at the national and provincial levels. For example, high-yielding, wind-resistant rubber varieties such as the sprouts of “thermal studies 917” support high-latitude rubber planting in china. The “south china 5” cassava was modeled in africa and produced significantly higher than local varieties, making it a highlight of agricultural cooperation in central africa。
“as china's only tropical province, hainan has invested in recent years in the exploration of tropical genre resources of great value.” in his presentation, wang jiabao, vice-president of the agricultural rural department of hainan province, the new collection of 1,180 copies of ancient, rare and unique local resources, and the selection of new varieties of bananas, such as the “middle fever 1” “bow island” which is highly resistant to aging, have addressed the current shortage of resistant banana varieties in the world。
The above-mentioned director of the department of agriculture and reclamation said that future efforts should be made to promote “five strengthening” such as better classification management, better investment of funds, better conservation and utilization, greater networking and enhanced cooperation in international exchanges, to explore the establishment of business-based systems for the commercialization of tropical crops and to accelerate the marketable development and utilization of new varieties of good tropical crops。
